Think the depth would be pretty much the same on the 11" round and 11x13. The longer coil is to cover more ground. Not sure how much more it weighs either.

I think it's going to depend on your soil minerals as to the depth you get. I've had all the coils made for the XP Deus. In my area the 11 x 13 is no deeper than even the 9 round. I've settled on the 9" round and elliptical coil for all my detecting. I really think the Deus was designed around the 9" round. It's well balanced and performs well in most scenarios.

In the areas I hunt the 9" X35 is the deepest of the three X35 coils due to similar bad soil conditions to Abenson. In milder dirt I don't think you would see too much difference between the 11" and 11"X13" X35 coils.  Hopefully Chase will respond since he has much more experience with this subject.

Kaolin washer, you could just private message Chase Goldman, tell him your ground conditions, target situation (bed of nails, etc), your typical settings and the depth you are trying to achieve.

About the weigths :

11 x X35   --> 470g with coil cover

13X11       --> 590g with cc

See :http://www.xpmetaldetectors.com/metal-detector/category/accessories-deus/

So quite a big weight difference between the coils ...

Concerning field results , I only know the 11 coil old version ( not the X35 ) , it is deep on big coins at depth in clean soils if you use a low freq like 5khz

trying to decide , 11inch coil x35 or the 11x13 x35 anyone have experience with both 

Frankly, the answer to this question is actually "it depends". 

But first lets dispense of the X35 11X13 coil.  Too heavy, no real performance benefit, and the increased swing coverage is not worth the added weight and shaft stress and potential loss of small target sensitivity.  Especially if you considered the exorbitant cost of Deus coils due to the electronics embedded in them.

Theoretically, the 11" is deepest but I am not sure it is really a measurable difference.  First of all, the ground conditions come into to play - in hot ground you are probably better off with the 9" round or even the 9x5 elliptical because the 11" will pick up more ground noise.  It's only real advantage seems to be swing coverage.  As others have said, the Deus just seems to be optimized around the 9" round coil.

My favorite coil is the 9" HF coil but it is limited to a minimum frequency of 13 khz which is a great "all around" frequency but you can get better depth at lower frequencies.  I like the HF coil because it accommodates 28 khz which to me seems to be a sweet spot frequency for relic hunting.

A better all around coil is perhaps the 9" x 35 because you can dial it down to less than 4 khz for max high conductive target (e.g.,, silver coin) depth.

The 9x5 obviously offers great separation but it also gets decent depth for its size and ok ground coverage, but it is certainly not the "deepest" coil.

Does the 9" HF have normalized scale or is that only on the x-35?

The original black Low Frequency coils and the new black X35 coils used with the Deus have an ID normalization On/Off choice. However, on the Deus there is no ID normalization choice for the High Frequency white coils, so it is automatically Off. So, basically, the HF coils are not fully compatible with the XP Deus............weird???

On the ORX, ID normalization is always On for both the white HF coils and the X35 coils. The ORX is not compatible at all with the original black LF coils.

In France/Europe we have hundreds of coin types/sizes/weights dating from the antic /medieval to modern ages , ranging from 0.5 to 30g so that we only use the VIDs as an indication , except in very specific situations . Perhaps that this is probably why XP has not really focused on this VID normalization  but rather on reactivity / iron filtering / ability on nail beds etc ... To summarize this VID feature is interesting but it is not the most important thing for us . Just my opinion as usual ...

Of course it would be better that those IDs are normalized as it is very useful in other countries like the US which are a big market for XP I imagine 🙂 ...

Interesting and good to know especially if I snagged one and use the tone breaks on key trash to help id good from bad. I ran into a snag with the standard scaling on the MK and ended up swapping back to normalized so I can jump frequencies and not have all my breaks and notches be out of whack.

This DD coil is completely waterproof and comes with a coil cover included.
      3. Fisher 11″ DD Search Coil for Fisher F70 and F75

      Fisher has a wide range of metal detectors it produces, from entry-level options to more professional-grade models. They produce a variety of search coils, both concentric and DD coils>, for all of their different metal detector series. The Fisher 11″ DD Search Coil for Fisher F70 and F75 is an excellent search coil that combines the larger search area of a D coil while providing the sensitivity and compactness of a concentric search coil. This coil not only detects targets deep in the ground, but it also performs very well in high soil mineralization areas. Treasure hunting with the Fisher search coil is a blast, as this coil is very light for its performance, which will keep you in the field longer.
      4. NEL Snake 6.5″ x 3.5″ Search Coil (AT Pro)

      NEL produces several aftermarket search coils that are compatible with a wide variety of metal detector makes and models. These coils are specialized and built with a specific purpose in mind. The NEL Snake 6.5″ x 3.5″ Search Coil (AT Pro) is designed for the specific purpose of metal detecting in trashy areas with your Garrett AT Pro metal detector. The unique design of the Snake allows for easy separation of non-ferrous and ferrous metal, helping you dig less junky signals. It really shines when you are specifically looking for small targets, such as gold nuggets and small jewelry. The NEL Snake is fully waterproof and will last for decades.
      Why Do I Need an Additional Search Coil?
      While many detectorists may go their entire lives treasure hunting with a stock coil, many others will find an additional search coil that complements their hunting style and habits in one way or another. There are a variety of reasons that someone might choose to invest an additional search coil, with these ranging from performance to area-specific issues.
      A search coil that you purchase has the potential to improve your metal detector’s performance in a big way. This improvement of performance is one of the most common reasons that people purchase a new search coil. Oftentimes, detectorists will look for a DD search coil or a concentric search coil that offers greater target depth or higher sensitivity, as this greatly improves the detector’s ability to find small targets at deeper depths. This is incredibly important, as many small objects, such as dimes, gold nuggets, and small relics, can be deep enough in the ground that a normal coil would not pick them up.
      Another common reason that hobbyists purchase additional search coils is that they can help them metal detect either more of the ground or for a longer period of time. To detect more of the ground, metal detecting enthusiasts pick out large DD search coils that can cover a lot of ground per swing. This is very beneficial in areas that are not filled with trash targets. In wide-open places, a large search coil can be a lifesaver, as you can go dozens of swings without hitting any targets. Another reason that people might prefer an additional search coil is if they are looking for a lightweight option. Some of the DD coils are very lightweight, especially the smaller sizes. It is amazing how much of a difference a few ounces on the end of your metal detector can make as the hunt progresses. Both of these reasons will help you find more targets and make better use of your time.
      A final reason that pushes detectorists to invest in an additional coil is area-specific problems. The problems can range from high soil mineralization to high trash areas. Finding the proper search coil for issues like these can help you be more efficient and will keep your hunts going smoothly. It is very hard to metal detect in areas with high trash volume if you are using a large search coil, and that is where the smaller coils come into play. Area-specific issues are always important to consider if you are deciding whether or not you should purchase a new coil.
      Which Metal Detector Coil Size Should I Purchase?
      When it comes to metal detector coils, it is important to keep your personal preferences in mind. One of the largest decisions you will have to make is the size of the search coil. There are advantages and disadvantages to both large and small coils. Depending on the situation, both options can be excellent for a variety of reasons discussed in detail below.
      Large Search Coils vs. Small Search Coils
      One of the biggest positive attributes for large search coils is their ability to cover a lot of ground with each swing. You will cover far more ground at the end of the day with a large DD coil compared to a smaller concentric coil. This benefit really shines in wide-open areas where there is not a ton of trash you have to contend with.
      Another big reason people like large search coils is their ability to detect targets that are deeper in the ground. As a general rule of thumb, the deeper an object is, the older it is in most cases. Big search coils produce a deeper magnetic field and the receiving part of the coil can intercept the detection of a metal target more easily. This increased detention depth is great for finding valuable relics, coins, and jewelry that other detectorists before you have missed.
      While there is a lot of upside to large coils, there are also some downfalls. One of the largest negative attributes of big search coils is that they are heavy. While larger search coils are only several ounces heavier than their smaller counterparts, this can make a big difference after an hour or so of swinging your metal detector. If you are planning on hunting all day long, a big coil may make you tire more quickly.
      Another disadvantage to big search coils is trying to hunt with them in high-trash areas. Trash targets include junk iron, can slaw, and a variety of other unwanted targets. Super sniper concentric search coils and other small coils are much better suited to hunting in trash-heavy areas.
      A disadvantage that is especially important for gold prospectors to consider is that large search coils are less sensitive to smaller targets. Gold prospectors are searching for small gold nuggets, and in many cases, a large search coil can swing right over them. Small coils, be them super snipers or any small DD coils can really help out in this area.
      One final disadvantage to keep in mind is that electrical interference and ground chatter occur more frequently with larger search coils. This is due to their increased magnetic field they produce and receive. If you have a metal detector with manual ground balance, this can be less of an issue, but it is still something to consider.
      How to Choose the Best Metal Detector Coil
      Determining which search coil is right for you will take some serious consideration on your part. With the wide variety of options and varieties available on the market today, it can be overwhelming to narrow down your wishlist. There are many things to keep in mind that will be discussed in more detail below, in addition to the discussion on the coil size above.
      DD Coils vs. Concentric Coils
      One of the more common questions that metal detectorists have is about the differences between DD coils and concentric coils. Choosing between a DD coil and a concentric may seem like a difficult choice, but the short answer is that both will perform very well. With that being said, there are a couple of differences. One reason many prefer the DD coil is the increased depth you can get out of it. In addition to the increase in depth, there is also a wider detection range and better target separation in many cases. With all that being said, concentric coils can be better in trashy areas or many other scenarios. The debate between DD and concentric is essentially based on personal preference and experience.
      Search Coil Compatibility
      Obviously, one of the more important considerations you will have to take into account is whether or not the search coil is compatible with your metal detector make and model. While most of the options available for each specific model will come from the manufacturer of that model, this is not always the case. Companies like Detech, Coiltek, and NEL also produce a wide variety of aftermarket search coils that are compatible with companies like Garrett, Minelab, Fisher, Bounty Hunter, Teknetics, and White’s metal detectors. At the end of the day, there are tons of options from a variety of manufacturers out there.
      Price of the Metal Detector Coil
      One of the most important considerations for most hobbyists is the price of the search coil. Buying a metal detector already represents a large investment in some cases. Forking over more money for a search coil can seem like a bad move. For this reason, many detectorists look for options that are within their price range. While these additional search coils might not have all the features of a more expensive one, they will still get the job done in whatever scenario you need them for. It helps to keep in mind that an additional search coil or two is an investment, as you will find many objects that will eventually pay it off.
      Conclusion
      When it comes down to it, choosing the right metal detector coil to invest in can greatly improve your metal detector’s abilities and provide you with a more efficient, fulfilling treasure hunting experience. Here at Kellyco, we make it a top priority to provide our customers with the best search coils on the market today.

      How hard is it to make the hard-wired coil cable on the compadre to a removable, plug in type?  I have two compadres; one with the 8” donut and the other with the 6”.  If I made them removable I could use them on my mojave and vice versa.  I’m pretty handy and can solder.  Just need a source for the connectors and which ones to get.

      Special thanks to Calabash digger for his reasearch on the pitch mode being good in iron , and His heads up on keeping the silencer at -1 so the target does not get masked in iron . well i used the pitch mode on the DEUS and kept the silencer @ -1 and it came thru for me , Got a good hit on many non ferrous targets today and some right next to iron . i was using the full tones but when i seen Calabash diggers VDs on the pitch mode i had to try that and it has proven to work very well  the VDI on this target was 49 and 50 right where a 22 casing comes in  or some foils . glad i dug it

      I’d have to say the Orx has been a successful venture for XP. But what comes next?  Their R&D must be working on a next generation detector, so what direction do you think they will go? An incremental change in existing technology or a whole new direction?  I haven’t a clue but I’m interested in what others think might be coming in the future, although right now I’m sure their focus is on getting their stock replenished after COVID
